Adsorption behavior of molybdate and tungstate from water by acid-treated carbon cloth was investigated. The carbon cloth was treated with sulfuric acid and used for the adsorption of molybdate and tungstate from water samples at nearly neutral solutions. The concentration of ions in the solution wa

Membrane processes have been used as a key technology for water reclamation and reuse of secondary effluent discharged from municipal wastewater treatment plants. However, its extensive practices are limited due to membrane fouling. To control and manage the membrane fouling properly, pretreatment m

Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those that are not easily biodegradable. Dyes represent one of the problematic groups. Natural zeolite was used as a low-cost adsorbent to evaluate its ability to remove color from effluents. In thi

An electrodialysis operation was performed to remove total dissolved solids (TDS) from polymer-flooding wastewater. The influence of flow rate and electrical potential on rate of TDS removal was studied during ! electrodialysis operation. Removal rate of the main ions in polymer-flooding wastewater

Membrane methods, including MF, UF and NF, belong to high-efficiency processes which can be competitive with traditional methods of water treatment. However, their efficiency can be affected by some parameters such as rejection and permeate flux. In this work, three membrane processes (MF, UF and NF

This paper aims at documenting the experience of the Environmental Research Center at the Royal Scientific Society in stakeholder participation in greywater management (treatment and reuse) in the rural communities in the northeastern Badia of Jordan. Stakeholders participating in the management pro

The vegetable sponge of cylindrical loofa, a natural product which grows in the north of Algeria, was used for phenol removal from wastewater. Adsorption isotherm of phenol onto the prepared cords of loofa was determined by batch tests. The effects of various parameters such as contact time, initial

Heavy metals such as cadmium, chromium and manganese are toxic priority pollutants that commonly interfere with the beneficial use of wastewater for irrigation and industrial applications. The sorption of cadmium, chromium and manganese from aqueous solutions onto natural sepiolite has been studied.

A theoretical comparison of neural network (NnM) and thermodynamic (ThM) models is carried out to estimate on-line the coefficient of performance (COP) in an absorption heat transformer integrated with a water purification process (AHT–WP). The NnM has been computed for16 variables measured by senso

The leaf sheath fibres of the Mediterranean seagrass Posidonia oceanica (L.) were used as low cost, available and renewable biological adsorbent for the removal of a metal complex textile dye from aqueous solutions. Batch experiments were carried out for sorption kinetics and isotherms. Operating va
